Green hit a red light when "something of concern popped up" during his physical, says ESPN Boston. There wasn't much of an explanation of what exactly was wrong with Green, but Celtics president of basketball operations Danny Ainge said it wasn't something of major concern.

"We found something in the physical that we anticipate is fine," Ainge said. "We just have to be real cautious."

Celtics coach Doc Rivers didn't have much information either.

"I really don’t know," Rivers said. "They’re still doing tests and all that kind of stuff. Honestly, I didn’t ask Danny [for an update on Monday]. I knew it already, that he wasn’t going to be here, so I didn’t give it a lot of thought... Danny told me don’t expect him the next couple days."

Ainge, according to boston.com didn't think Green would miss too much time because of the undisclosed injury.

"Oh no, no, no, we're not even close to that," he said. "It's just precautionary, practice just started today officially when we have our whole team here. It will be resolved this week."

Scalabrine looking for a contract

Former Celtic fan favorite Brian Scalabrine has left Italy in hopes that he'll play in the NBA again.

During the lockout, Scalabrine was playing for Benetton Treviso, a professional basketball team in Italy, but with the lockout lifted, he's back and looking for a contract. Head coach Alexander Djordjevic wasn't pleased that Scalabrine abandoned his Italian team. From NESN:

"He hasn't a team and an NBA contract yet. I was counting on his professionalism, respect for the club and especially for his young teammates. He could help us at least until tomorrow, the team needed it."

It is uncertain whether Scalabrine has been talking with teams or is just confident in his ability to play in the NBA again, but wherever he goes, he will be a solid addition off the bench.-NESN

Pavlovic re-signed

The Celtics are slowly but surely filling out their roster as Christmas Day approaches.

Boston announced Monday that they re-signed Sasha Pavlovic and came to terms with rookies JaJuan Johnson and E'Twaun Moore.

According to WEEI, rookies cannot be traded for at least 30 days after they sign contracts. So it looks like they'll be around at least for the beginning of the season. With the opening day match up set for Christmas Day against the Knicks, the Celtics still have work to do to fill the roster.

"We knew coming into the summer that we had limited resources and it’s proven to be very challenging," said Ainge. "It's been a chaotic week. There’s been a lot of time put in, but we’re still trying to build our roster. But we liked the guys that we’ve signed and the team that we have."

Ainge didn't say whether or not the Celtics were done making moves or if they had more up their sleeve.

Pressed if the team needed another big, Ainge noted, "Yeah, probably so. That would be nice. And not just big, but somebody who can play and is big."
